The mid credit scene had Shang Chi, Wong, and Katy meet with holographic "Zoom meeting" Captain Marvel and Bruce Banner. They discussed something magical involved with the rings as a beacon for souls. Which I assumed it was Wanda's kids reaching out somehow in whatever dimension they are trapped in. Sorry for the vagueness.
The end credit scene was Shang's sister taking over their dad's empire, looks like she overseeing a force of elite soldiers
